the trainer GMP works for you guys? mine doesn't add any amount when i press the key.( i set mine to 10k )
Yes it does and I just checked it again. Did you:
Download the latest new trainer? They posted two new ones back to back. Might dload it again to be sure.
Set the game for OFFline mode?
Have the iDroid open?
Make sure you deleted any and all older trainers.
